What causes landslides to happen?
Landslides can be triggered by heavy rainfall, earthquakes, volcanic activity, human activities such as construction or deforestation, or changes in slope stability due to factors like erosion or changes in underground water flow. When the force of gravity overcomes the strength of the materials holding the slope in place, a landslide can occur.
What sphere do landslides take place in?
Landslides primarily take place in the geosphere, which encompasses the solid, rocky parts of the Earth's surface. They occur when the stability of the earth materials is compromised, leading to the mass movement of rock, soil, and debris down a slope.
How do land slides occur?
While gravity and friction will hold loose material, cohesion within rock surfaces is also important. Anything that reduces the friction (such as water), or reduces cohesion (such as a tremor) or adds potential energy (more rock, structures, people, vehicles) can cause the material to slide downhill over the underlying material. When stress is greater than strength,the slope becomes unstable and slope failure may occur. A landslide is a kind of slope failure.
What is true about landslides?
Landslides are a mass of moving rocks, debris and soil. Landslides can occur in any area, although some areas are more prone to landslides (for example: California). A landslide can occur when the force of gravity overcomes the force of friction that holds a sloped mass in place. A landslide could be triggered by the movement created by an earthquake, or simply from saturation by rainfall or other moisture sources.
What time of day do tsunami's occur and which place's?
Tsunamis can happen at any time of the day or night, as they are typically triggered by underwater seismic activity such as earthquakes, landslides, or volcanic eruptions. They occur in coastal regions around the world where these events take place, such as the Pacific Ring of Fire and areas with subduction zones.
What are the main factors that contribute to landslides occurring, and why do landslides happen in the first place?
Landslides occur due to a combination of factors such as steep slopes, heavy rainfall, earthquakes, and human activities like deforestation and construction. Landslides happen when the force of gravity overcomes the strength of the materials holding the soil or rock in place, causing them to move downhill rapidly.

How often does deforestation occur in Africa?
Deforestation occurs because people want money and the wood market is a big money maker but you have to put roads in place and much more.
What will happen when deforestation or cutting trees occurs?
there will be more landslides as trees will not be there to hold land in place. flooding as trees won't be there to soak up the water, and more co2 because trees get rid of it.

Where is earthquakes most likely to occur?
earthquakes are most likely to occur on the rim of tectonic plates
What is the effect of landslides on wild life?
landslides can destroy animals habitat and therefore they won't have a place to live.
When will there be deforestation?
There was some in the first place.
